No need Cargo.toml but still respect it if it's there

[DrSensor]

Just got some info that you can compile rust code without Cargo.toml using rustc. Also, command cargo rustc will respect Cargo.toml ⎝✧ᴥ✧⎠

future plans

Seems I can replace cargo build with cargo rustc?
Also, using --emit flags and pipe it as a return value seems to be a good idea. Some projects need to import different .rs file which mean there will be multiple compilation. This cause out-dir to be rewrited multiple times 😞
